Rethink Under Deck Drainage | Sluiceway Landscaping | Sawdust EP05

Water is everywhere when you’re working on the coast, and that’s we’re talking about on Episode 5 of SAWDUST.
We start with a visit to Site Superintendent Garrett Kirwin at a waterfront build in Matunuck, Rhode Island where we have a classic coastal building situation. There’s a second story deck in an area well known for wind-driven rain, and our client wants to make the most of the space below with a furnished 3-season room. Applying years of experience in the business. Garrett has developed a custom drainage system for the rooftop deck that has us rethinking best approaches!
Next, we meet up with framing crew leader Ryan Sweenor for a “My Toolbelt” segment that will not disappoint.
Our final stop is back at the historic grist mill where we’re talking water, but this time, the name of the game is how to harness it to power the mill. Jon Zeyl and his team Landscape Creations have teamed up with us to give back to the South Kingstown Land Trust and our local community. They’re donating services to improve the sluice way that feeds the Samuel E. Perry Grist Mill and strengthen the weir at its water source, aptly named Mill Pond. Tune in as Jon explains the construction repairs that will give 300-year-old hydro-power technology a new future.

These are great, I would also recommend putting the self sealing flashing tape on the boards before hammering in the nails. It’s what I do to make sure that pressure treated doesn’t ever rot.

[@bobbray9666]

The sheet metal formed in between decking joists, prior to installing decking, seems like the best idea for waterproofing the space under that I've seen. I think the only way to make this work is to make sure the deck slants 1/4"/foot away from the house for proper drainage. If the deck was slanted less than that, the sheet metal forming would need to get progressively deeper away from the house, which would make the metal bending more complicated and cost more than if all way bent the same way. I'm going to built a deck above a walkout patio door next summer. I was looking at locking aluminum decking but the cost is really steep. Other alternatives are either using something like roofing membrane, which looks bad underneath as the membrane sags between joists or the many under deck solutions that looks like a lot of neck wrenching work. My deck will be 11' off the ground. I'm seriously thinking of drawing up a galvanized sheet metal profile and sending out to local sheet metal shops for a quote. I can always paint the underside of the metal before installing. I'd use joist flashing tape over the metal edges on the joists and that should seal well even with nails and screws going though the flashing when installing.

[@DennisB3533]

Great idea just a couple suggestions, 1) someone already brought up the point of the non galvanized nails and the pressure treated lumber and the problems that will eventually arise but the pressure treated lumber will cause the metal to deteriorate also, I would put a peel and stick tape like what you use around windows between the 2X4s and the metal to keep the lumber from reacting with the metal. 2) find a metal roofing company with a 20’ brake and they can make your trim in solid pieces so you don’t have to overlap. Again great idea I’ll use it myself thanks guys

[@Sweenorbuilders]

Great Suggestions Dennis! Thanks!

[@matttanglewood2522]

Second the idea of putting down the adhesive membrane first. That will isolate the metal pans from the p.t. wood ( along with the other benefits of protecting wood if there is any standing water on it). Still have to deal with fasteners. Could use copper roofing nails to secure it, but then have galvanic reaction problem between copper nail and metal pan. Could just hold the pans in place with 2nd application of flashing tape? Better yet, make the pans out of copper instead of sheet metal ( what are you guys, a bunch of cheap skates 😂🙄).

[@kennethyoung3911]

You might want to add some synthetic mesh at the bottom end of those deck sleeper channels. Remember in RI we have fall hornet season. Those nice dry spaces would be great for nesting locations. Just a thought.

[@GregDiBernardo]

The debris will still collect on the metal. The sleepers are protected but now you can get synthetic purpose made sleepers that won't rot.

[@c4fishfood]

I expect the metal will self clean a bit better however, the triangular sluice will concentrate water and the texture of the metal is smoother than the rubber, making the flow velocity a bit higher to better carry sediment away. Also, there isn’t the same nook and cranny problem where sediment will build up in the 90 deg corners of the sleepers. I would be curious how this system weathers with time.

[@TheWhaleman64]

Make the last row of deck boards removable (at the house) to spray a garden hose down periodically.

[@mikemorgan5015]

What holds the deck down? You've essentially created another membrane when you tied the sleepers together. A strong wind at the end of the channels will want to lift the whole deck. Where does the air between the rubber and the metal escape in high wind situations?

This is exactly the system that I came up with, minus full flat membraned base; but you got me considering it lol.

[@michaelgrifoni2160]

Good call on preventing homes in the cavities, I shall need to consider this too. If I think of a good idea I’ll run it by you; please let me know if you come up with something first. It think the bug netting idea would work, just need it to be removable/trap door style so you can do clean outs

Hello! Would you mind commenting on the double water proofing? What I mean is, why do both waterproofing layers and not one or the other? It seems like the metal and Gtape works well and there isn't any need for the flatroof waterproofing underneath. Also, can the 2x4 runners eventually dry out and not rot? Thanks!

[@jacobkrzyzek5777]

How does the water drain? Are the sleepers not ripped to correct the slope of the rubber roof deck?

[@TriDaddy]

How are the treated 2x4's sleepers attached to the roof deck so they don't move? Or is it a completely floating deck?

[@rockys7726]

So if you have a sheet metal trough and tape over the seams do you really need the rubber membrane underneath? And where do I get this sheet metal? Do I have to make it myself?

That is a very awesome detail for roof drainage under a deck. Simple and even washable from the upper deck, nice work. Agree with the others. Taping is a good idea on top of those PT members.

[@rupe53]

With the metal under the decking I have to wonder if that will also clog with debris then back up toward the house? Working on a flat roof leak under a sleeper deck as I type here. As I see it, the only thing you might gain is a few extra years on the roofing material due to no UV issues. My roof is 35 years old right now and even with PT wood that also splits / warps with time so needs replacement every 20 years or so.... even when stained for extra protection.

the deck drainage system is brilliant!!! quick question... bc the sleepers are not fastened in any way... do they warp, twist or move... and when you walk on it.. are there spots that thump as your foot adds pressure...

Great question. Very possible. The deck screws help a little bit, but it is wood, and it’s an imperfect system. We try to avoid using PT straight off the shelf, and give it some time to dry, because the dryer it is the less it will move. A week of drying will weed out some of the crappy boards. The grain will give hints on how the wood is going to move, but time is the best judge. Hope that helps
